The Blue Ridge Parkway's lowest tunnel clears just 11'7" at the edge — and 25 of its 26 tunnels are in North Carolina
Of the 26 tunnels on the Blue Ridge Parkway, 25 are in the North Carolina section. Tunnels are arched, so the posted height is two numbers — centerline (max) and edge (min) — and the edge dips well below center. Big Witch Tunnel near Cherokee is the lowest at 11 feet 7 inches at the edge, and several others sit just over 13 feet. Measurements can vary 1-6 inches with pavement. Measure your rig's total height including A/C shroud and antennas, and stay near centerline; rooftop gear scrapes the arch long before the center clearance runs out.
